As shown in Sec. ., in general, when the light coming from an AGN is \(\ge \)  25% of the total galaxy light, most of the used morphological parameters and therefore the morphological classification of AGN host galaxies can be significantly affected. We found that the classification of early-type galaxies (elliptical and lenticular) hosting an AGN will be more accurate than when dealing with spiral and peculiar hosts. Difficulties in classifying late-type galaxies in comparison to early-types have been already observed in the past, e.g., when studying the effect of survey resolution and depth on the morphological classification of galaxies [1]}.
